# CVE-2026-93995: Apache MINA SSHD: Remote execution of JGit "archive -o=file.zip" can write file on the server

> Authenticated SSH clients can write arbitrary files on the server by exploiting insufficient input validation in the git archive command.

- **Severity:** Medium 6.5 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N`)
- **Exploited in the wild:** Not known

- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 30 Sep 2026

## What is CVE-2026-93995?

CVE-2026-93995 is a medium-severity path traversal vulnerability in Apache MINA SSHD, published on 30 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Improper input validation in sshd-git in Apache MINA SSHD, versions up to 2.19.0 and 3.0.0-M1 to 3.0.0-M5. Apache 
MINA SSHD is a Java library for client-side and server-side SSH.

Component org.apache.sshd:sshd-git provides though class GitPgmCommandFactory a way to configure an Apache MINA SSHD server such 
that authenticated SSH clients can remotely execute git commands via the JGit library 
on git repositories stored on the server. In CVE-2026-58624 this mechanism was restricted to only a few git commands, including "git archive" without "--output" or "-o" options such that the resulting archive would not be written on the server but instead sent back to the client over the SSH connection.

The fix done for CVE-2026-58624 was insufficient as it missed removing the single-argument "-o=file.zip" version of the command parameter from the "archive" command.

Users are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.

Weakness: CWE-20 (Improper Input Validation)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-93995 and fix it if it is affected.

What it is: CVE-2026-93995 is a medium-severity path traversal vulnerability in Apache MINA SSHD, published on 30 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-93995 in the wild and no public exploit code.

Affected product: Apache MINA SSHD. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
